Preparation of sterically congested 1,3,4-oxadiazole derivatives from N-isocyaniminotriphenylphosphorane, aromatic acids, cyclopentanone and primary amines
Reactions of N-isocyaniminotriphenylphosphorane with cyclopentanone have been studied in the presence of aromatic carboxylic acids and primary amines, proceeds smoothly at room temperature under neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives by an intramolecular Aza-Wittig cyclization in CH2Cl2 in excellent yields. The structures of the products were deduced from...

متن کاملIdentification and Analysis of the Migration of Primary Aromatic Amines from Flexible Food Packaging by High-performance Liquid Chromatography (HPLC)
Background and Objectives: Primary Aromatic Amines (PAAs) are contaminants that can migrate from food flexible packaging. The main origin of these compounds is polyurethane adhesives used in the laminating process of multilayer films. Residual aromatic di-isocyanates of the reaction of adhesive polymerization migrate into the food, and are hydrolyzed to PAAs by the moisture of food. 2,4- and 2,...

متن کاملHypervalent phenyl-λ3-iodane-mediated para-selective aromatic fluorination of 3-phenylpropyl ethers.
Exposure of 3-phenylpropyl ethers to an activated iodosylbenzene monomer·18-crown-6 complex [PhI(OH)BF(4)·18C6] in the presence of BF(3)-Et(2)O and water results in the para-selective monofluorination of benzene ring via neighboring alkoxy group participation and directly affords 3-(4-fluorophenyl)propyl ethers regioselectively in good yields.
